White smoke could be for a number of reasons.
First, make sure it’s not overheating. I believe Monte’s have an coolant gauge in the dash.
Second, do a pressure test and see if the head gasket is messed up.
Bad timing can also cause heating issues from what I understand.
And if all of that is good- then it’s probably a leaking exhaust manifold. Don’t worry about it.
